The blood circulation system in human spleen: is it open or closed?

Open or closed system of blood circulation in the spleen? This issue has been debated for many years. However, a consensus between the authors representing opposing viewpoints on hemorrhage in the spleen has not been established to date. The purpose of the study is to provide data on morphological-functional features of the blood circulation system in the human spleen. The work was performed on spleen preparations (n=17) of people of different ages. Injectional and histological methods of investigation were used. The obtained data testify to the extremely complex blood vessels architecture of the human spleen, which includes an open also and closed blood circulation system.
